Bifoliate Cattleya with uncertain origins

[bogdan]

I have this Cattleya from 5 years ago, when it was given to me without a tag, but with the "verbal tag" of guttata. It clearly isn't a guttata, as the plant size (small) and the relative lack of spots do not correspond.

I am thinking that this might be some sort of granulosa. Perhaps schoefieldiana? The fragrance has not yet developed itself, the flowers opened yesterday. What is your opinion?

Thank you!
